14. A student hypothesizes that an increase in pressure will increase the amount of ammonia produced in the reversible reaction shown. 2NH3(g) N2(g) + 3H2(g) nitrogen hydrogen ammonia Which best explains how an increase in pressure increases the amount of ammonia present? O An increase in pressure favors the product with fewer particles. O An increase in pressure tends to increase the temperature of the gases. O An increase in pressure would cause the forward reaction to be endothermic. An increase in pressure decreases the rate of reaction between gases. PREVIOUS 14 of 25 NEXT US AM9 Lit hp ce esc &
